Redundant array length check

Reports unnecessary array length checks followed by array iteration. When array length is zero, the iteration will be skipped anyway, so there's no need to check length explicitly.

Example:

void f(String[] array) {
  if (array.length != 0) { // unnecessary check
    for (String str : array) {
      System.out.println(str);
    }
  }
}

A quick-fix is suggested to unwrap or remove the length check:

void f(String[] array) {
  for (String str : array) {
    System.out.println(str);
  }
}
